Redsn0w_0.9.9b1 Released!

As promised MuscleNerd of iPhone-Dev has just released redsn0w 0.9.9b1
with some major improvements. New version of redsn0w, redsn0w 0.9.9 b1
comes with tons of new feature including automatic device detection in
DFU mode and now you don’t need to select IPSW manually, it will detect
and download required files from Apple servers for you.

Redsn0w 0.9.9b1 works on same device and firmwares but remeber it won”t
detect or download iOS 5 beta files because they’re meant for developers
only. You’ll have to manually select iOS 5 Beta IPSW files.

Here’s the complete change log and release notes of redsn0w 0.9.9b1:

A bunch of new features!

* uses DFU mode to try to automatically determine which device and FW you have
* fetches pieces of public IPSWs from Apple (once). Non-public IPSWs
must be provided manually (once). It then caches those pieces for
future use.
* "Just boot" is a tethered boot. Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
* "Pwned DFU" puts your device in a pwned DFU state for some of the iTunes stuff detailed below
* "Recovery fix" gets past 1015 types of errors (when baseband portion of restore fails). Should work on iOS5 beta too
* "Select IPSW" is for picking non-public IPSWs, or overriding auto-detection
* "SHSH blobs" has a bunch of options…
* "Fetch"– fetch current PARTIAL blobs on device. Puts this set PARTIAL
of blobs on your computer as a plist. Checks if Cydia already has a
full set for this device and build. If not, it submits this partial set
and returns Cydia’s acknowledgement or rejection
* "Verify" – cryptographically verifies existing blob files from either
redsn0w, TinyUmbrella, or Cydia server. You can select a whole bunch
of blobs to verify at once if you want (like the TinyUmbrella directory)
* "Submit" – both verifies and submits one or more blob files to Cydia.
This lets you copy your entire TinyUmbrella cache of blobs up to the
Cydia server
* "Query" - queries the Cydia server for all available full or partial blobs for a given set of ECIDs
* "Stitch" – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW

1. FULL blobs stitched to a STOCK IPSW gives you a completely
self-contained signed IPSW that iTunes will accept without any tricks
(no need to go into pwned DFU mode, no need to start TinyUmbrella TSS
server, no need to redirect to Cydia server for blobs)
2. PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU
mode before running iTunes. No need to start TU or use Cydia though.
3. stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires
a pwned DFU start before iTunes restores. No need to start TU or use
Cydia though.
4. stitching is NOT yet supported on iPhones (well, at least not
tested). Need to work out the baseband part of the restore process.
5. will eventually support fetching the blobs directly from Cydia instead of a file on your computer
